Abstract (en)
[origin: EP0862069A2] An optical fiber includes a core, a first cladding, a second cladding, and a third cladding. The core has a refractive index n0. The first cladding is formed around the core and has a refractive index n1. The second cladding is formed around the first cladding and has a refractive index n2. The third cladding is formed around the second cladding and has a refractive index n3. The refractive indices have relationships n1 > n2 > n3 and n1 > n0. <IMAGE>
